"The Philly Post" blog reported on research showing that regional "accents" are developing in the Twitterverse. Muffy Siegel, a linguist at Temple, says sites such as Twitter have given those who study language a treasure trove of information to sift through and analyze. "Social media have proved a bonanza to linguists, because it gives us access to people writing and speaking in a very natural way. We didn't have access to people's social interactions this way before without sneaking up on them with tape recorders."

From doctors to bartenders, there's no shortage of people offering advice about alcohol. What's fact and what's fiction? Recent research calls some conventional wisdom into question. For example, contrary to popular belief, drinking coffee will not get you sober faster. Caffeine may keep you awake, says Temple psychologist Thomas Gould, but it won't lower your blood alcohol level. In fact, a cup of coffee may make it harder for you to realize you're drunk, he says.
